,{Since the abuttingcouplers of the cars are similar in construction;only one of said couplers willbe described. A. coupler head 3. ismounted on the stem 3 and provided with a tappedfhole 14 to receive aconnection-to the train pipe. The head is provided with ports 16, 17 Ahose-coupling pipe18 is connected tothe head 3 and is adapted to beengaged by the ordinary hose-coupling or fluid r'pressure .brakeapparatus.

A valve 19 supported by an arm 20 on a rock shaft 21; mounted .inbearings on. the

- g coupler head is normally heldlbythe action ofthespring 22in theposition in which it closesthe'outlet or portf17. One end of thespring'22 bears againstthe pipe 18 and the other isattached totherock-shaft 21. ,At- 1 an intermediate point in its length this springextends across an arm or finger 23 'which isjloosely mounted on therock-shaft 21 and-projects therefrom in such position. that .it will beengaged by a projection or 3 member on a cooperating coupling head asSpecification of Letters Eaterit."

the two heads are brought together for the purpose of bringing the ports17 thereof into alinement. This causes a rocking of the shaft 21 andshifts the valve 19 into the dotted position shown in Fig. 2, thusopeningthe port '17 and closing the port 16 that communicates directlywith the hose-coupling pipe 18. The two heads of the coupling be ingthus related and the ports 16 closed, the brakeman by opening suitablevalves brings the train pipes on the two cars into'communication withthe ports 17. i

In case it is necessary to couple a car h'aving a train pipe couplingconstructed in accordance with the presentinvention with a car havingmerely the ordinaryhand hose coupling the latter is. engaged by couplingpipe 18 and as a spring'holds the va1ve'19 in position to close the port17 the train "pipes on the two cars will be connected through the port16 and hose coupling pipe 18 when the valve in the train pipeis open. y

, In theembodiment ofthe inventionillustrated the coupling head isprovided at onL side with a funnel-shaped guide 2t'and at theoppositeside with a pin mounted on an arm 25 and adapted to cooperatewith a funnel guide 21 on the opposite head, and the finger or arm 23 onthe valve actuating rock shaft 21 extends across the aperture or openingformed at the reduced end of the funnelshaped'guide members. Thereforewhen the two coupling heads are brought together the pins on the arms 25will each move the arms or-fingers 23v of the other and therebyautomatically shift the two valves 19 away from their nominal positionacross the port 17 and cause the valves to close the port 16.

The above construction thus briefly described is illustrated anddescribed at length in our patent referred to and does not form thesubject matter of the present invention.

As shown a suitable bushing 26 is secured within the port 16 of .thecoupling headand adjacent the outer end thereof isformed a concave seatinto which is fitted a gasket 27 of soft rubber and which is circular incross section. The inner seat for the'gasket 27 is formed partly by agroove in the inner face of the bushing 26 and partly by a ring 28 whichis arranged in. a groove 29 in the bushing, and, through the gasketextends a sleeve 30 the-inward movement otwhichis limitedv by a shoulder31 Within the bushing. The sleeve 30 is provided with a flange portionadapted to engage'the gasket 27 and hold the latter on its seat. v

A bowed spring or locking member 32 is adapted to retain the sleevewithin the bushing while permitting a limited movement' thereoflongitudinally, The length of the spring locking member 32 is greaterthan the diameter of thesleeve 30 extending around the interior of thesleeve over'more than one-half, but over less than threefou'rths of'theinterior circumference of the sleeve and in order that the latter may beintroduced into the bushing said locking member is turned into theposition indicated in Fig. 3, inwhich position its ends will liesubstantially flush with the outer surface of the sleeve. After thesleeve has been inserted in the bushing a slight presv I sure onthe bodyof the locking member 32 willfshift it into the position indicated inFig. '2 where it extends'directly transverse of the diameter of thesleeve and thereby the bent ends thereof will be projected throughapertures in the sleeve 30 and into a groove 33 formed in the bushing.The length of thespring locking member 32 is suchthat when in place itextends around more than half of thecircumference of the sleeve 30 andbears against the interior surface of the latter.fl By spacing theapertures in the sleeve so that they are not diametrically opposite oneanother, the ends of the spring 32which extendv through the sleeveand-lock the: latter in the groove'33 will be automatically withdrawnfrom' the aper- 1 and 4:; By exerting a slight pull on the portion ofthe locking device 32 Within the sleeve it may be shifted into theinclined position indicated in Fig. 3, thereby withdrawing its ends fromengagement with the bushing and permitting the sleeve to be withdrawnand the gasket released.

It will be seen that the locking member 32 doesnot completely fill thegroovef33 and that there is a slight space between the adjacent walls ofthe sleeve and bushing. VW'hen the coupler is in use, that is when thetwo coupling heads are brought together as shown in Fig. 2 with the port17 in alinement, the pressure of the fluid within the coupling headsacts against the rings 28 and through them against the gaskets 27 whichare thus held in close contact with the bushing. and sleeve and incontact with each other; 7 Since the gasket 27 is constructed of softrubber it may lie entirely back of the metal surfaces at the contactfaces of the coupling heads when the couplers do not form an operativeconnection. In addition the soft rubber construction has the advantagethat the gasket is not broken dueto the sudden jar occasioned by thecoming I together of two coupling heads.

1 It isobvious that various changes may be i made in the details ofconstruction without departing from this invention and it is therefore-to be understood that this invent1on is not to be limited tothespecific construction shown and described.
